当序列化类"App \ Entity \ User"的对象时，已经检测到循环引用.(配置的限制:1) [英] A circular reference has been detected when serializing the object of class "App\Entity\User" (configured limit: 1)
问题描述
我遇到了一个导致此错误的问题:
I am faced with a problem that gives me this error:
序列化以下对象时检测到循环引用类"App \ Entity \ User"(配置的限制:1)
A circular reference has been detected when serializing the object of class "App\Entity\User" (configured limit: 1)
我有一个企业实体，其中包含任务订单，车辆和用户.
I have an Enterprise entity that has mission orders, vehicles, and users.
与用户，公司和车辆有关系的订单实体.
An orders entity that has a relationship with a User, Company, and Vehicle.
还有一个与订单和公司有关系的用户实体.
And a User entity that has a relationship with orders and company.
所以我有这个: Entreprise.php
class Entreprise
{
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* @ORM\OneToMany(targetEntity="App\Entity\User", mappedBy="entreprise", orphanRemoval=true)
*/
private $users;
/**
* @ORM\OneToMany(targetEntity="App\Entity\Vehicule", mappedBy="entreprise", orphanRemoval=true)
*/
private $vehicules;
/**
* @ORM\OneToMany(targetEntity="App\Entity\OrdreMission", mappedBy="entreprise", orphanRemoval=true)
*/
private $ordreMissions;
OrdreMission.php:
class OrdreMission
{
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* Agent qui réalisera la mission
* @ORM\ManyToOne(targetEntity="App\Entity\User", inversedBy="ordreMissions")
* @ORM\JoinColumn(nullable=false)
*/
private $user;
/**
* Immatriculation de la voiture de service
* @ORM\ManyToOne(targetEntity="App\Entity\Vehicule")
*/
private $vehicule;
/**
* @ORM\ManyToOne(targetEntity="App\Entity\Entreprise", inversedBy="ordreMissions")
* @ORM\JoinColumn(nullable=false)
*/
private $entreprise;
Vehicule.php:
class Vehicule
{
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* Marque du véhicule
* @ORM\Column(type="string", length=255)

private $marque;
/**

private $modele;
/**

*/
private $immatriculation;
/**

*/
private $entreprise;
User.php:
class User implements UserInterface, Serializable
{
/**
* @ORM\Id()

private $id;
/**

private $email;
/**

* @ORM\Column(type="json")
*/
private $roles = [];
/**
* Ordres de mission de l'utilisateur

*/
private $ordreMissions;
/**

*/
private $entreprise;
/**

*/
public function serialize()
{
return serialize([
$this->id,
$this->email,
$this->password,
]);
}
/**
* Constructs the object
* @link http://php.net/manual/en/serializable.unserialize.php

public function unserialize($serialized)

}
当我要添加新车时，出现错误消息:
When I want to add a new vehicle, I get the error:
序列化以下对象时检测到循环引用类"App \ Entity \ User"(配置的限制:1)
A circular reference has been detected when serializing the object of class "App\Entity\User" (configured limit: 1)
我在互联网上看到我必须做一些最大深度"的事情，但是我不明白我必须做些什么，确切地在什么地方
I saw on the Internet that I had to do something with a "maxdepth", but I do not understand what I have to do and where exactly
这是我用来添加Vehicle Object并将其发送的功能控制器:
This is the function controller that I use to add a Vehicle Object and send it:
/**
* Pour créer un nouveau véhicule
*
* @Route("/chef-service/ordres-mission/new/new-vehicule", name="vehicule_create")
* @IsGranted({"ROLE_CHEF_SERVICE"})
* @Method({"POST"})
* @return Response
*/
public function createVehicule(Request $request, EntityManagerInterface $manager)
{
$vehicule = new Vehicule();
$vehicule->setEntreprise($this->adminService->getEntreprise());
$form = $this->createForm(VehiculeType::class, $vehicule, [
'action' => $this->generateUrl($request->get('_route'))
]);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$encoders = array(new XmlEncoder(), new JsonEncoder());
$normalizers = array(new ObjectNormalizer());
$serializer = new Serializer($normalizers, $encoders);
$manager->persist($vehicule);
$manager->flush();
$result = $serializer->normalize(
[
'code' => 200,
'message' => 'OK',
'vehicule' => $vehicule,
],
null,
[AbstractObjectNormalizer::ENABLE_MAX_DEPTH => true]
);
$jsonContent = $serializer->serialize(
$result,
'json'
);
return new Response($jsonContent);
}
return $this->render('ordre_mission/partials/newVehicule.html.twig', [
'formVehicule' => $form->createView(),
]);
}
推荐答案
尝试通过使用序列化组来避免循环引用(Symfony序列化器和jms序列化器均适用).当您序列化用户"而不序列化其他实体的用户"时的示例.
Try to avoid circular reference by using Serialization Groups (work for both Symfony Serializer and jms Serializer). Example when your serialize "User" don't serialize "users" from other entity.
用户
class User
{
/**
* @Groups("user")
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* @Groups("user")
* @ORM\ManyToOne(targetEntity="App\Entity\Entreprise", inversedBy="users")
* @ORM\JoinColumn(nullable=false)
*/
private $entreprise;
}
企业
class Entreprise
{
/**
* @Groups("entreprise")
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* @Groups("user_detail")
* @ORM\OneToMany(targetEntity="App\Entity\User", mappedBy="entreprise", orphanRemoval=true)
*/
private $users;
然后
$json = $serializer->serialize(
$user,
'json', ['groups' => ['user','entreprise' /* if you add "user_detail" here you get circular reference */]
);
不过，您还有两个选择，可以使用处理循环引用或使用处理序列化深度
However you have two more option either use Handling Circular References or use Handling Serialization Depth
